DNA 'origami' could help build faster, cheaper computer chips

Electronics manufacturers constantly hunt for ways to make faster, cheaper computer chips, often by cutting production costs or by shrinking component sizes. Now, researchers report that DNA, the genetic material of life, might help accomplish this goal when it is formed into specific shapes through a process reminiscent of the ancient art of paper folding.

A nanoparticle does double duty, imaging and treating atherosclerosis

Scientists have developed a nanoparticle that functionally mimics nature's own high-density lipoprotein (HDL). The nanoparticle can simultaneously light up and treat atherosclerotic plaques that clog arteries.

Nanomotors could help electronics fix themselves

As electronics grow ever more intricate, so must the tools required to fix them. Anticipating this challenge, scientists turned to the body's immune system for inspiration and have now built self-propelled nanomotors that can seek out and repair tiny scratches to electronic systems.

Experiment shows magnetic chips could dramatically increase computing's energy efficiency

In a breakthrough for energy-efficient computing, engineers have shown for the first time that magnetic chips can operate with the lowest fundamental level of energy dissipation possible under the laws of thermodynamics.

Spray-on coating could ice-proof airplanes, power lines, windshields

Thin, clear and slightly rubbery to the touch, the spray-on formula could make ice slide off equipment, airplanes and car windshields with only the force of gravity or a gentle breeze.

New fuel cell design powered by graphene-wrapped nanocrystals

Researchers have developed a new materials recipe for a battery-like hydrogen fuel cell - which surrounds hydrogen-absorbing magnesium nanocrystals with atomically thin graphene sheets - to push its performance forward in key areas.

Soap bubbles for treating stenosed blood vessels

Liposomes are currently used as drug delivery vehicles but recognized by the immune system. Scientists have now shown that special artificial liposomes do not elicit any reaction in human and porcine sera as well as pigs.
